Problems solved by technology

But the loudspeaker of the existing plant audio frequency generator is generally a single ordinary loudspeaker, and the installation position is fixed. At a certain moment, the sound wave signal can only be applied to the crops at a specific height in a certain direction, and the sound wave signal cannot be simultaneously applied to the surrounding area of ​​the loudspeaker. crops, and it is difficult to apply to crops of different heights (or the height of crops has changed during different growth periods), which greatly reduces the efficiency and scope of application of plant sound frequency generators

Abstract

The invention relates to a sound amplifying apparatus for a plant acoustic frequency generator which belongs to the technical field of sound wave processing in physical agriculture. The sound amplifying apparatus comprises a base, an elevating structure and a sound amplifying device. The base is a truncated cone with a cavity structure and is provided with a sliding door. The elevating structure comprises two identical connection blocks (I and II), four identical incomplete gears, four connecting rods with identical structure, screw nuts, support plates, screw rods, and adjusting handles. The sound amplifying device consists of four identical cylindrical shape loudspeakers arranged in a parallel connection manner. The sound amplifying device is fixed to the support plates through support columns; the backs of the support plates are connected to the upper end of the elevating structure and the lower end of the elevating structure is connected with the base. The height of the sound amplifying apparatus can be adjusted and sound waves come out in four directions at the same time, which substantially increases the working efficiency and the application scope of a plant acoustic frequency generator.

Description

technical field [0001] The invention relates to a sound-speaking device of a plant sound-frequency generator, which belongs to the technical field of sound wave processing in physical agriculture. Background technique [0002] With the rapid development of global agriculture, my country's agriculture is in the process of transforming from traditional chemical agriculture to ecological agriculture, and the way of transformation is mainly realized by combining bioengineering and physical agriculture. Plant audio frequency control technology is an important aspect of physical agriculture. Its basic principle is to play a specific frequency of sound waves to act on plants in a specific environment, so that it matches the natural sound frequency of plants, so that plants can resonate, thereby increasing Large plant stomata, thereby enhancing its photosynthesis, promoting its growth and development, reducing the use of chemical fertilizers and pesticides while meeting high-efficie...
